White nectarine tree named ‘NECTARSAFIR’

ABSTRACT

A new and distinct variety of white nectarine tree denominated ‘NECTARSAFIR’ which has fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet white flesh at maturity time, and a red pigmentation into and around the stone cavity, and an attractive skin with a very high percentage of luminous purple red blush on skin surface, on a red background.

Botanical classification: Prunus persica (L.) Batsch.

Variety denomination: ‘NECTARSAFIR’.

This application claims priority of Community Plant Variety Right No. 2020/3064 filed on Nov. 30, 2020 (Nov. 30, 2020) which is hereby incorporated by reference in its entirety.

The new variety named ‘NECTARSAFIR’ is also known as 9C.02.250.16 NB or ASF17134. Indeed, before giving a name to a new and distinct variety of fruit tree, a provisional reference is assigned, considering the references of a tree in orchard. This provisional reference is constituted firstly with the number of the parcel on which the tree has grown, then the number of the line, the tree number and finally the year of selection. Then before being named ‘NECTARSAFIR’, the provisional reference of this white nectarine tree variety was 9C.02.250.16, corresponding to the tree 250 located in line 02 of the parcel 9C and selected during the year 2016. The letters “NB” are related to the first letters of the type of tree in French (NB for “Nectarine Blanche”, that means “white nectarine”). Once the hybrid selected, the breeder assigned a clone reference that begins with the letters “ASF” followed by the year of selection and a number corresponding to the maturity order. The final name is only assigned once the application, has been filed and the name approved after its publication in the official bulletin. For the variety ‘NECTARSAFIR’, the clone reference was ‘ASF17134’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white nectarine tree, Prunus persica (L.) Batsch, which has been given the variety denomination ‘NECTARSAFIR’.

This new tree produces fruits with a long shelf life without alteration both on the tree after growth completion and after harvesting, very good eating quality, semi-clingstone white flesh fruits, generally with a red pigmentation around and into the stone cavity, for fresh market in August in the Pyrénées-Orientales department, France.

ORIGIN OF THE VARIETY

The ‘NECTARSAFIR’ white nectarine tree originated from a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested.

This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontane’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘NECTARSAFIR’ variety results from controlled pollinated cross between the white nectarine variety named ‘NECTARPERF’ (U.S. Plant Pat. No. 23,357) which was used as the seed parent, or female parent, and the white flat nectarine variety named ‘CAKEREDAL’ (U.S. Plant Pat. No. 23,358) which was used as the pollen parent, or male parent.

The ‘NECTARSAFIR’ variety was obtained by hybridizing and propagated by grafting on a ‘INRA® GF677’ (non-patented) rootstock trees. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of the standard rootstock trees set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree, and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées-Orientales, France. More particularly, the plant was reproduced by grafting.

SUMMARY OF THE VARIETY

The new and distinct variety ‘NECTARSAFIR’ white nectarine tree blooms during the first two weeks of March near Elne in the Pyrénées-Orientales department, France. The blooming period is considered medium. However, it was observed that its date of blooming seems to be highly dependant on climatic conditions.

The first fruit of ‘NECTARSAFIR’ ripens generally medium in the season, namely at the end of July or at the beginning of August. However, it was observed that its date of maturity seems to be highly dependant on climatic conditions.

DETAILED BOTANICAL DESCRIPTION

The trees, flowers, and fruits may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruits by ‘NECTARSAFIR’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are medium vigorous and large stature half-standing in a semi-flared out aspect. The anthocyanic coloration of flowering shoot is present excluding brushwood side away from sun. The time of beginning of flowering is considered medium; flowering begins at the beginning of March. The type of flower is showy (rosette) with medium petal size. Petals are pink. Leaf glands are present and intermediate (round or reniform). The fruit flesh is white at complete maturity. The fruit flesh usually shows a red pigmentation into the stone cavity and radiating around the stone cavity. The fruit skin is medium thick, with a luminous purple red blush on a red background. The stone is semi-clingstone and its size is small. Fruit taste is semi-sweet, aromatic and with a high level of sugars.

Compared to ‘NECTARDREAM’ white nectarine variety (U.S. Plant Pat. No. 23,420), the fruits of ‘NECTARSAFIR’ usually ripen during the same period. However, the fruit skin of the new variety ‘NECTARSAFIR’ shows a luminous purple red color covering 90% of the skin surface, on a red or pink background, whereas the fruit skin color of the ‘NECTARDREAM’ white nectarine is less colored, namely with a garnet red color covering 60 to 90% of the skin surface. Moreover, the background of the skin of the ‘NECTARDREAM’ variety is considered green to cream green.

The fruit flesh of ‘NECTARDREAM’ is washed green whereas the fruit flesh of the new variety is white with a slightly pink coloration.

Compared to its seed or female parent, i.e., the ‘NECTARPERF’ (U.S. Plant Pat. No. 23,357) variety, the new variety ‘NECTARSAFIR’ has a later blooming period. Namely, the first flowers of ‘NECTARSAFIR’ bloom approximately 15 days later than the flowers of ‘NECTARPERF’.

The first fruits of the new variety ‘NECTARSAFIR’ ripen one month earlier than the fruits of the variety ‘NECTARPERF’.

The fruit skin of the new variety ‘NECTARSAFIR’ is more uniformly colored than the fruit skin of ‘NECTARPERF’.

Compared to its pollen or male parent, i.e., the ‘CAKEREDAL’ (U.S. Plant Pat. No. 23,358) variety, the new variety NECTARSAFIR has a later blooming period. Namely, the first flowers of ‘NECTARSAFIR’ bloom approximately 15 days later than the flowers of ‘CAKEREDAL’.

The first fruits of the new variety ‘NECTARSAFIR’ ripen one month later than the fruits of the variety ‘CAKEREDAL’.

The fruit skin of the new variety ‘NECTARSAFIR’ is more uniformly colored than the fruit skin of ‘CAKEREDAL’.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white nectarine tree, the following was observed on trees in their fourth growing season (third year of production) under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales departement, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘INRA® GF677’ (non-patented) trees. All major color code designations are by reference to The R.H.S. Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree:     -   -   Size.—         -   Generally.—Considered large. The tree size the first year             was approximately 200 to 280 cm. The tree was pruned during             each following dormant season to a. height of approximately             250 cm. Current season shoots growth could reach 80 cm. The             tree size from the second year (second and next years)             reached a final height of 330 cm including current season             shoots length. The tree size is consistently reduced to 250             cm the next years.         -   Spread.—Approximately 100 cm with a cylindrical shape. The             whole orchard was oriented to a central leader organization,             with tree lines spaced of 4.0 meters and trees spaced of 1.0             meter in a same tree line. As a result, tree spread was             about 100 cm and the orchard contained 2500 trees by             hectare.         -   Vigor.—Considered strong.         -   Productivity.—Considered good to very good, and very             regular. Fruit set is spaced by thinning to develop the             remaining fruit into the desired market sized fruit. The             number of the fruit set varies with the prevailing climatic             conditions and cultural practices employed during the bloom             period and is therefore not distinctive of the present             variety. A reduce vegetation, obtained with pruning or green             pruning, approximately 1 month or 1 month ½ before             harvesting fruits, significantly promotes fruit qualities,             especially growth, color and firmness. Moreover,             contamination risks due to Monilia or rot are significantly             reduced. ‘NECTARSAFIR’ variety is not much sensitive to             cracking of pistil cavity, to cork formation into peduncle             cavity or to Monilia.         -   Bearer.—Very regular. The fruit distribution is considered             homogenous on mixed branches and spurs having more than 1             year. Thinning of 2 fruits out of 3 was necessary for the             tree valorisation. Thinning was necessary every year during             the years of observation.         -   Form.—The ‘NECTARSAFIR’ variety has naturally a semi-flared             shape.         -   Density.—Considered dense.         -   Hardiness.—Hardy in all stone fruit growing areas of France             and especially where the chilling requirement is between 700             and 1200 hours. More particularly, experimentations on the             same orchard in Elne, Pyrénées-Orientales department, with             winter chilling requirement below 7.2° C. comprised between             700 hours and 1200 hours according to the specificities of             the year, namely 1031 hours in 2012-2013, 777 hours in             2013-2014, 893 hours in 2014-2015, 718 hours in 2015-2016,             825 hours in 2016-2017,1017 hours in 2017-2018, 844 hours in             2018-2019, 706 hours in 2019-2020 and 822 hours in 2020-2021             showed a good behavior of the tree in all cases. No injury             with temperatures as low as −12° C. in winter. Good             resistance to late frosts. -   Trunk:     -   -   Diameter.—Approximately 65.0 to 72.0 millimeters in diameter             when measured at a distance of approximately 20.0             centimeters above the soil level for trees on fourth leaf             (or third year of production).         -   Bark texture.—Considered rough, with lenticels.         -   Lenticels.—Numerous lenticels are present. The number of             lenticels reaches 2 lenticels per cm².The lenticels range in             size of approximately 4.0 to 6.0 millimeters in width, and             about 1.5 to 2.0 millimeters in height.         -   Lenticel color.—The lenticels show a beige color (RHS Greyed             Orange 165 D).         -   Bark coloration.—The bark has a grey color (RHS Grey Green             197 A) darker than the lenticels color. -   Branches:     -   -   Size.—The branches are pruned to approximately 1.0 meter in             length.         -   Diameter.—Average as compared to other nectarine varieties.             The current season shoots have a diameter of approximately             5.0 to 6.0 millimeters, and mature branches have a diameter             of approximately 7.0 to 9.0 millimeters.         -   Surface texture.—Smooth for current season shoots and rough,             with lenticels, for mature branches, wood which is several             years old has no furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally 45 degrees from the             horizontal axis for current season shoots and 65° degrees             from the horizontal axis for mature branches. This             particular characteristic is not considered distinctive of             the variety, however.         -   Current season shoots.—         -   Internode length.—Generally 22.0 to 28.0 millimeters.         -   Color.—The color of new shoot tips is considered light green             (RHS Yellow Green 145 A) on lower part of new shoot tips,             whereas the upper part is darker and colored in purple (RHS             Greyed Red 183 A), depending on the level on the tip and the             sunlight exposure.         -   Mature branches.—         -   Internode length.—Generally 26.0 to 32.0 millimeters.         -   Color of mature branches.—Brown (RHS Greyed Brown N 199 B or             RHS Greyed Brown N 199 A).         -   Lenticels.—Numerous lenticels are present on mature             branches. The number of lenticels reaches 3 lenticels per             cm². The size of lenticels is considered small on one year's             old shoots and medium on two-year-old shoots. The lenticel             shape is stretched round with a diameter of approximately             1.0 to 1.5 millimeter on one-year-old shoots and a diameter             between 1.5 and 2.0 on two-year-old shoots.         -   Lenticel color.—The lenticels on mature branches have a             beige color (RHS Greyed Orange 165 C). -   Leaves:     -   -   Size.—Considered medium for the species. The ratio leaf             length/leaf width is 3.577.         -   Leaf length.—The medium length is about 130.20 millimeters             with leaf petiole.         -   Leaf width.—The medium width is 36.40 millimeters.         -   Leaf form (in cross section).—Concave.         -   Leaf form.—Lanceolate.         -   Leaf base shape.—Round.         -   Leaf tip form.—Acute.         -   Leaf thickness.—Medium.         -   Leaf color.—         -   Upper leaf surface.—Yellow Green (RHS Yellow Green 147 A).         -   Lower surface.—A slightly lighter green (RHS Yellow Green             146 A) than the upper leaf surface color.         -   Leaf texture.—Smooth and glabrous on both upper and lower             surfaces of the leaf.         -   Leaf venation.—Pinnately veined.         -   Mid-vein.—         -   Color.—Light green, almost cream white (RHS Yellow Green 145             A or RHS Yellow Green 145 B). The color may evolve with             maturity.         -   Width.—Approximately 1.5 millimeters.         -   Secondary veins.—         -   Color.—Light green (RHS Yellow Green 145 C).         -   Leaf margins.—Slightly undulating.         -   Form.—Considered crenate.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, one leaf of normal size is found with one or             two smaller leaves (at least 50% smaller).         -   Leaf petioles.—         -   Size.—Considered small.         -   Length.—About 8.0 to. about 10.0 millimeters.         -   Diameter.—About 1.0 to 1.5 millimeters.         -   Shape.—Grooved.         -   Petiole color.—         -   Upper petiole surface.—Green (RHS Yellow Green 144 A or RHS             Yellow Green 144 B).         -   Lower surface.—A slightly lighter green (RHS Yellow Green             144 C) than the upper petiole surface color.         -   Leaf glands.—         -   Size.—Considered medium. Their length is about 1.0             millimeter and their width is about 1.0 millimeter.         -   Number.—Generally 2 glands per leaf.         -   Type.—Intermediate, round or reniform.         -   Margins.—Smooth and regular.         -   Position.—Alternate on the upper part of petiole.         -   Color.—On young leaves, leaf glands color is considered a             light green (RHS Yellow Green 145 A). On older leaves, leaf             glands color turns to a brown (RHS Brown 200 A or RHS Brown             200 B) color.         -   Leaf stipules.—         -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers:     -   -   Flower buds.—         -   Generally.—At pre-floral stage of development, the floral             buds are conic in shape. Their form is evolving until             blooming, with variable dimensions. Just before blooming,             floral buds are approximately 8.0 to 9.0 millimeters wide             and approximately 10.0 to 12.0 millimeters long. The floral             buds show a homogenous distribution on the trees.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flower's buds, or calyx, or flower receptacle, is of             purple color (RHS Greyed Purple 187 A or RHS Greyed Purple             187 B) on its outer face. The inner face of the flower             receptacle is orange yellow (RHS Greyed Orange N163 B or RHS             Greyed Orange N163 C). The corolla, formed by the petals, is             generally of pink color (RHS Red Purple 65 A or RHS Red             Purple 65 B) on both faces. Petals color shows an evolution             until the end of flowering.         -   Hardiness.—The buds are considered hardy under typical             central Pyrénées-Orientales departement climatic conditions.             No winter injury was noted during the last several years of             evaluation in the central Pyrénées-Orientales departement,             with winter temperatures as low as −10 degrees Celsius in             January. The current variety has not been intentionally             subjected to drought or heat stress, but the variety showed             a very good resistance in orchard to temperatures up to 42             degrees Celsius with an average temperature between 28 and             30 degrees Celsius during 3 weeks in summer.         -   Date of bloom.—The blooming time generally begins early in             March. The first bloom was observed on Mar. 1, 2018.         -   Blooming time.—Considered medium in relative comparison to             other commercial nectarine cultivars grown in the             Pyrénées-Orientales departement, France. The date of full             bloom is observed generally at the middle of the blooming             period. The date of bloom varies slightly with climatic             conditions and cultural practices.

The juice shows a cream             color.         -   Brix.—Generally between 12.8 and 14.0 degrees. The medium             Brix is 13.3 degrees. This characteristic varies slightly             with the number of fruits per tree, prevailing cultural             practices and the surrounding climatic conditions.         -   Flesh color.—The flesh is considered white (RHS White 155 A)             and becomes pink at complete maturity, usually with a red             pigmentation (RHS Red 47 A) into the stone cavity and             radiating around the stone cavity on approximately 3.0 to             4.0 millimeters. -   Stone:     -   -   Type.—Semi-Clingstone, more or less semi-adherent depending             on the fruit maturity.         -   Size.—Considered small for the variety. The stone size             varies significantly depending upon the tree vigor, crop             load and prevailing growing conditions.         -   Length.—Approximately 25.0 millimeters.         -   Width.—Approximately 20.0 millimeters.         -   Diameter.—Approximately 16.0 millimeters.         -   Form.—Elliptical.         -   Base.—Round.         -   Apex.—         -   Shape.—The stone apex is short and pointed.         -   Stone cavity.—Considered small in size, with round form and             dimensions corresponding to the stone's dimensions.         -   Stone surface.—         -   Surface texture.—The pit is transversely furrowed on its             entire surface. Furrows are deeper and more oblate on             lateral sides.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and at the             apical tip.         -   Ventral edge.—         -   Width.—Narrow. Approximately 2.0 millimeters at mid-suture.         -   Dorsal edge.—         -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is generally             considered light brown (RHS Greyed Orange 164 B or RHS             Greyed Orange 164 C).         -   Tendency to split.—Splitting is absent.         -   Kernel.—         -   Size.—The kernel is considered small.         -   Length.—Approximately 12.0 millimeters.         -   Width.—Approximately 7.0 millimeters.         -   Thickness.—Approximately 5.0 millimeters.         -   Form.—Considered elliptical.         -   Pellicle.—The pellicle of the kernel has a short pubescence.         -   Color.—The kernel skin is brown colored (RHS Greyed Orange             N167 A). The almond, which is the seed of the kernel, is             white (RHS White 155 B) and has a sweet taste. The kernel             and its embryo are mature at the time of fruit maturity.         -   Use.—The subject variety ‘NECTARSAFIR’ is considered to be a             white nectarine tree having a medium season of maturity, and             which produces fruits that are considered firm, attractively             colored in purple red. Fruits have semi-sweet taste and are             excellent for uncooked consumption, crunchy or melting when             at full maturity. Fruits have excellent gustative qualities.             Due to their flesh quality, firmness and density, they can             also be commercialized as 4th range product (packed fruit or             fruit in bags for example). And they are also useful for             both local and very long-distance shipping.         -   Keeping quality.—Remarkable. Fruits have a slow maturation             and a long shelf life both on the tree after growth             completion and after harvesting without alteration. After             growth completion, fruits are preserved more than one week.             After harvest, fruits are well preserved more than 2 weeks             at 2.0 degree Celsius.         -   Shipping quality.—Considered very good. The fruit of the new             white nectarine variety showed minimal bruising of the flesh             or skin damage after being subjected to normal harvesting             and packing procedures. Its resistance to handling during             harvest and packing and its long shelf life without             alteration after harvest easily permit 2 weeks-shipping at 2             degrees Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety is not very             sensitive to Monilia or rot. The pistil cavity is completely             closed, generally without any cork formation.

Although the new variety of white nectarine tree possesses the described characteristics when grown under the ecological conditions prevailing near Elne, Pyrénées-Orientales departement, France, it should be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control and horticultural management are to be expected. 

I claim:
 1. A new and distinct variety of white nectarine tree as illustrated and described, characterized by fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet white flesh at maturity time, and a red pigmentation into and around the stone cavity, and an attractive skin with a very high percentage of luminous purple red blush on skin surface, on a red background.
